WINDOW-REGULATOR SLIDE.

Application filed July 28,

T 0 a]? whom it may concern:

Be it known that I. ERXEST E. HEINTZ. a citizen of the United States, residing at De troit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in indow-Regulator Slides, of which the following is a specification.

This invention relates to an actuating slide for a window regulator. In a previous application Ser. No. 435,597, I have described a. window regulator which is actuated by a slide which travels on a track below the garnish molding of the window. The object of the present invention is to afford an improved slide which is substantially as effective as the slide shown in my previous application but which is much cheaper to manufacture. This slide is made up of substantially only three parts which are stampings that can be formed by easily made dies.

In the drawings,

Fig. 1 is a side elevation of a window regulator.

Fig. 2 is an enlarged side elevation of the actuating slide. i

F ig. 3 is a vertical cross section through the track.

Fig. 4 is an enlarged view of one of the clutching levers.

Fig. 5 is a view showing the clutching levers pinched together to permit the slide to travel along the track.

Fig. 6 is a perspective of the body of the slide showing the guide in phantom lines.

Fig. 7 is a detail erspective view of one of the pins used to pivot the levers.

In my previous application I have shown in detail a window regulator of this type. Suflice it to say that a designates the lower rail of the sash, b the link secured to the aforesaid rail. This link is connected with a lever c which has a shifting fulcrum at d. The second lever e is fulciumed at f and forms with the lever c a pair of toggle levers. An arm 9 is pivoted to the bell crank lever h and also to the lever c. This arm 9 and the lower end of the bell crank lever h form a pair of toggle arms. When these toggle arms are straightened out they serve to straighten out-the toggle levers and lift the sash. When these toggle arms are folded up they serve to fold up the toggle levers and lower the sash.

This bell crank lever h is connected to the shown in 5. This lifts the shoes 4: from 1921. Serial No. 488,223.

slide or carriage j by means of the link i. This slide is simply a flat stamping Zr: havlng its center depressed at 6 to afford space for a pair of clutching levers m and n. Lever n has a pair of teeth 0 in which engages the single tooth p of the lever m. These levers are pivotally supported on a screw machine product or stud g (detailed in Fig. 7). This stud is provided with a reduced portion at one end which is flattened on one side. This reduced portion is arranged to fit into the punched openings 8 in the body stamping it. The end of the reduced portion may then be upset. This securely anchors the studs to the body. Of course, before the stud is anchored in place the lever is fitted over the stud and seats upon the central cy-v lindrical portion of the stud. An annular flange or portion of larger diameter 25 serves to hold the lever in place. The free end of the stud is slotted as at w to anchor the wire springs y. This wire spring abuts against the turned back lug e on the clutching lever and tends to force the clutching lever into engagement with the guide 1. This guide 1 is simply a shallow channel having the flanges 2 turned out to form tracks over which engage the track-engaging flanges 3 punched out of the body is. The bottoms of the levers are turned over to form shoes t which afford a greater surface area for frictionally engaging the slide guide. From the above description it will be evident that the parts are all stampings with the exception of the wire springs and the studs, the latter of.

which may be screw machine products.

lVhen the window is raised to any point above its lowest position it will be evident that the weight of the window will tend to reverse the window lifting parts and thereby pull the slide along the guide. However,

this effort is exercised at considerable disadvantage, due to an adverse leverage. Consequently the force tending to pull the slide along the guide is small, namely, the weight of the window diminished considerably by anadverse leverage. Hence a small amount of resistance will be suflicient to hold the window in any position. This resistance is afforded by the levers which have-their shoe portions urged into engagement with the channel guide by thesprings 3 Now When one takes hold of the lever ends with the hand the levers pinch together as is plainly contact with the slide guide and the slide is 4. An actuating slide for window regula- 3:

free to be moved and thereby actuate the sash. Q

What I claim is: I

1. An actuating slide for window regulators, having in combination with a channel guide, a body arranged to slide on the guide and a pair of levers pivoted to the body and having shoe portions in rubbing contact with the channel walls, said levers serving for both releasing the body and moving the same.

2. An actuating slide for window regulators, having in combination with a channel guide, a body arranged to slide on the guide and a lever pivoted on the guide and provided with a shoe portion in rubbing contact with the guide wall and a, spring for forcin the shoe portion into contact with the guide, the said lever serving for both releasing and moving the body.

3. An. actuating slide for window regulators, having in combination with the guide a body arranged to slide on the guide, alever pivotally supported on the body a stud for supportmg the lever upon the body comprising a portion riveted to the body, a portion seating the lever, an annular flange for holding the lever in place and a free end portion having a slot; and a spring anchored in said slot and bearing against the lever for holding a portion of the lever in rubbing contact with the guide until the lever is grasped to actuate the slide.

tors, having in combination with a channel guide having turned out flanges forming tracks, a body provided with track-engaging flanges and a lever pivotally supported on said body and having a portion in rubbing engagement with the channel guide until the lever is grasped to actuate the slide and yielding means for holding the said lever in such engagement with the slide.

5. An actuating slide for a window regulator, having in combination with a channel guide having turned out flanges forming tracks, a body in the form of a stamping having a pressed out central portion and end portions having struck out track-engaging flanges, and one or more clutching levers supported in the depressed portion of the I body. I

6. An actuating slide, having in combination with the guide a body engaging with the guide to slide therealong, a pair of levers pivotally supported upon the body and having inter-engaging teeth, the resistance ends of said levers arranged to engage in rubbing contact with the guide and spring means for normally holding the levers ends in said rubbing contact, the said levers, when grasped, actuating the slide thereby releasing the resistance ends from rubbing contact with the guide. I

In testimony whereof I aflix my signature.
